Writes of voyage and his work in natural history: geology, collecting insects (freshwater beetles and spiders at Botofogo Bay); life at sea, sublime views ashore.

Has been away from parish because of a three-month illness. Refers briefly to events in England since the Beagle sailed.

He is staying on the Isle of Wight because he has been unwell. He is thought to be in danger of contracting consumption, and the climate is beneficial. He is convalescent now, but will spend the winter there.

Offers to forward any natural history stores CD may want.

Sketches the Beagle’s travels – Rio de Janeiro, Montevideo, cruise to the south and return – and what the future holds. Writes with nostalgia of England and says he sees no end to the voyage.

He enjoys and has been lucky principally in geology and among pelagic animals; has found remains of large extinct animals.
